Слайд 4Environment Overview
Through this course,,,
We will use Ubuntu LINUX as the
base OS for the projects.
Do we need new machine for Ubuntu LINUX?
We usually use Windows OS for our own machine
The answer is NO!
We have “Virtual Machine Environment”!
Such as VMware Player

Слайд 5Environment Overview
What is “Virtual Machine Environment”?
Software Stack of “Virtual Machine Environment”
Physical
Resources of Your own machine
(CPU, MEM, STORAGE, NETWORK ..)
(CPU, MEM, STORAGE, NETWORK ..)
Host OS (e.g. Windows)
(Your host OS installed on the machine)
VMware Player
(Virtualization Layer from VMware)
Слайд 6Install Virtual Machine Monitor
“Virtual Machine Environment”
Download VMware Player (https://my.vmware.com/web/vmware/free#desktop_end_user_computing/vmware_workstation_player/12_0) or
(http://core.kaist.ac.kr/~djshin/VMware-player-12.0.0-2985596.exe)
Depends on
your OS
Windows-64bit
Linux-64bit
You need 64-bit Operating System.
If you don’t have, please contact TA.
Слайд 7Install Virtual Machine Monitor
Install VMM
Install the product following the instructions of
the installer
Installation Path
Enter your e-mail
Run VMware Player
Слайд 8Install Guest OS
We’ll use Linux OS for Guest
Linux
made by Linus Torvalds
in 1991
Free software for replacing Unix
Many usages - servers, desktops, mobile devices(Android)
Linux Distributions
Operating Systems based on Linux Kernel
Linux Kernel : Core of Linux
Scheduling, File System, Device Drivers
System Software : Compilers, Libraries, User Interface
User Program : Office, DB, Web Server, Web Browser, Mail …

Слайд 11Install Guest OS
Virtual Machine Properties
Disk Size : 20GB is enough
Need free
space in HDD
Main Memory Size for VM
more than 1GB
Number of processor for VM
Слайд 12Install Guest OS
Initialize Ubuntu Desktop
it takes several minutes.
log-in with your password
open
terminal (ctrl + alt + T)
Слайд 13Install Guest OS
Get root account & password
root account : the highest
level account for administrator
It is needed when
change system configuration
install programs
execute system-level program
It is needed when
change system configuration
install programs
execute system-level program
cannot reboot
create root password
you are the root now
Слайд 14Shell Script
Shell
A command line interpreter
Accepts input from the user
Executes the
command that is given
Types of Shell
Command Line Interface (CLI) shell
Based on text
Graphic User Interface (GUI) shell
Based on graphic
e.g. x-window system in linux

Слайд 15Shell Script
Various CLI Shells
Bourne Shell (1977) == sh
Developed by Steve Bourne
@ AT&T Bell lab.
First shell of UNIX system
Bourne-again shell (1989) == bash
Developed by Brain Fox
Basis of shells on UNIX/LINUX type system
Recent systems also use bash

bash shell : Ubuntu default
bourne shell (sh)
Слайд 16Shell Script
CSH (C shell)
Developed by Bill Joy
C-language-like shell interpretation
TCSH (Tenex C
shell)
Tenex: OS from Carnegie Mellon Univ.
Enhanced version of CSH for Tenex system

Слайд 17Shell Script
Command execution on Shell
ls : List information about file(s)
cat :
Display the contents of a file
echo : Print string
mkdir : Create new folder(s)
rmdir : Remove folder(s)
pwd : Display current directory
cd : Change current directory
cp : Copy one or more files to another location
mv : Move or rename files or directories
rm : Remove files
echo : Print string
mkdir : Create new folder(s)

pwd : Display current directory
cd : Change current directory
cp : Copy one or more files to another location
mv : Move or rename files or directories
rm : Remove files
Слайд 18Writing a Shell Script
Text Editor
gedit : GUI based text editor
vi, vim
: CLI based text editor
apt-get install vim
you can use any text editor
apt-get install vim
you can use any text editor
install vim
ubuntu:~$ gedit
ubuntu:~$ vim test.sh

Слайд 22Make Utility
Utility for automatically building executable programs and libraries from source
code
Help build programs from numbers of source code files
Manage dependency among source code files and compiling method
Prevent mistake
$ gcc –o hello hello.c
? Correct
$ gcc –o hello.c hello.c
? source code will be gone!

Слайд 23Make Syntax
Syntax
:
$ make program
Will compile “program”
After all compilation of
others because of dependency
This empty space should be “tab” not “space”
Слайд 25Macro of Makefile
Similar as “#define” of C programming
Useful for repeated expression
Below
will do same compilation as previous slide
$ make all : compile every BINs
$ make clean : delete every BINs
$ make all : compile every BINs
$ make clean : delete every BINs
Слайд 26Task1. Tree Script
Write a bash shell script that shows tree structure
of the directories and files included in you own home directory.
Example of Task1
Слайд 27Task2. Simple C Program
Benchmark
Computer program in order to assess the relative
performance of an object, normally by running a number of standard tests and trials against it
We can make File System Benchmark!

File create ? Sequential Write
? Sequential Read ? Random Write ? Random Read ? File Delete ? End
You should Implement 3 functions
You can refer “file_write_sequential()” function
void file_read_sequential() : about 20 lines
void file_write_random() : about 25 lines
void file_read_random() : about 25 lines
